LISA M Motor Yacht

I've bought the above kit to keep me busy during these dark dank winter months. Originally I had planned to build a 880mm (34.6") Bluebird of Chelsea plank on frame kit. It is a famous pleasure craft built for Sir Malcolm Campbell and took part in rescuing soldiers from the beaches of Dunkirk under 'Operation Dynamo' in 1940. Unfortunately much to my bitter disappointment only the larger 52" version now is available which is too big for myself.
I'm hoping some kit builder will make a kit of this craft at about 36" so in the meantime here goes with LISA M

The kit has an ABS hull (a bonus for my hands these days!) and laser cut plywood parts. The kit also comes with an electric motor so all you need is a servo and speed control plus the usual R/C gear and battery.
A set of English instructions were also provided which are a reasonable translation with the odd error here and there! I feel they could be a bit more specific in places so study the photos.

The ABS hull comes with about 1 1/4" (about 300mm) extra height above the deck level which needs cutting down to be about 2mm above the temporary fitted deck level. This wasn't that easy but in the end I used a pair of tin snips to cut it which proved to be better than using a Stanley Knife. I have drilled and filed the holes in the ABS hull for the prop shaft tube and rudder tube. I've now assembled the deck coaming, motor mount, battery box and supports for the rudder tube. Next job is to waterproof the deck on both sides, and all the other assembled plywood parts. Having seen another blog, I've decided to strengthen the wood around the rudder tube by using an offcut from the wood provided for the boat stand. I will smooth the edges when the glue has set!

Slow progress!

Slow progress as I've been dragged into doing some decorating! Anyway the internal motor mount, battery box, and rudder post have had 3 coats of sanding sealer and 3 coats of blue spray paint. I've also on the advice of Chum, I've added some strengthening to the ABS hull using 1.5mm plastikcard and hard plastic glue which smells like contact glue!

    +++ I would also add a couple of beams from port to starboard after you have figured out the layout of running gear. Make sure their position doesn’t limit access to any component you may need to access in the future.

I don't know what I've done wrong - if anything

Got to building the superstructure and I have come across an unexpected problem! the main part of the superstructure appears to fit fine but the aft cockpit well will not fit inside the boat! On discovering this I pulled the cockpit well apart before the glue set completely!! Has anyone else experienced this potential problem with this Krick Lisa M build or is it my fault? I've attached relevant photos from the manual and also pictures of the boat and cockpit (with one side removed!) Any suggestions please?

    Is A a different length from B ? See photos

    What is the measurement from one side of coaming to the other?

    Hi Donald,

    It is unlikely that you have done anything wrong.

    When building from a kit (or a plan) it is not at all unusual to have to do a little "fettling" to make minor adjustments to make parts fit together correctly.

    You would be welcome to pop over to my crowded workshop(shed) sometime if you would like me to take a quick look with you.

    I have never built a Krick kit, but I expect the above comments would apply to it as much as they do with any other kit or plan build.

    Bob.

It now fits !

I've removed the tabs from one side to reduce the width of the cockpit well and then glued the cockpit well side back on. Hopefully there will be sufficient clearance for the paint layers! I had to also widen the slots in the main superstructer to accommodate the shorter width of the cockpit well. The photos show the dry test so next job is to glue them with some extra strengthening on the inside of the cabin and then fill the slot gap in the superstructer. Just a bit of a unexpected problem to overcome! Thanks for your suggestions and offer of help from Zooma.

Lower superstructure now complete

I decided to change the order of the build from those in the manual. I therefore added the cockpit coaming strips before gluing the cockpit floor well to the main superstructure. This enabled me to have the cockpit well in the correct position within the hull before gluing with superglue the main cabin structure to this cockpit. After the glue had set I added strengthening pieces around the inside of the joints and these pieces also covered the larger than required gaps I had created in the main cabin to take the slimed down cockpit well. I then filled gaps in the build including around the window frames etc with Holts Knifing Putty. I sanded the cabin before putting the roof on as some areas otherwise would be difficult to reach! I used Titebond Ultimate to attach the roof in order to give me more time to get the roof aligned correctly as this gives a lot more time to adjust the positioning than using superglue! I think I will next apply a primer coat before building and adding the upper section of the 'fly deck'.

Painting almost complete

Filling, sanding and painting has taken quite a long time! After two coats of sanding sealer, two coats of primer / undercoat applied by brush I then sprayed two coats of white. So far I've applied one coat of blue to the hull below the water line. The small can of spray paint has now run out so I need to buy another tin of paint to give a second coat. I was disappointed that the kit didn't contain the blue flashes that appear down the rear side of the superstructure. I managed to resource from Amazon a pack of different coloured self adhesive plastic sheets for £4.49 which I thought was a great price. In the instructions it says use brass wire for the hand rails but they supplied two lengths of stainless sheets rod which is thinner (1mm rather than 1.5mm) which means you don't have to open the eyes of the split pins. I found I was short of the plastic for the final window in the door so I had to use some that was fortunately left over from a previous build. I used some plastikard to make the front skylight hatch and covered this with the black sticky backed plastic sheet. I used one of my wife's crafting beads to finish off the top of the ladder hand /support rail. I've still got to finish the decks with at least another coat of paint and put some of the fittings on. Fitting the bridge for the radar scanner is turning out to not be that easy so I'm having a break from it by creating this posting!🤣🤣
